Structually floored tent

I bough a Campmaster, Camp Dome 410 tent at Makro for a camping trip in December. <br> Upon pitching it, I discovered that the tent has an inside groundsheet that is attached to an outside groundsheet with a ground-level seam. Such seams always leak and so all tents are made with the groundsheet seam off the ground (usually about fifteen centimetres).<br> <br> Of course, whenever it rained, the water ran in through this seam, flooding my tent. <br> <br> This is not a junk tent and as far as I am aware, Campmaster is not a junk brand. So I returned the tent, expecting to be refunded or allowed to swap the tent for one without this ridiculous design floor (ie a normal dome tent with no attached groundsheet extending outward). Instead I wasted hours in Makro's barely functional returns system and after two months was given my original tent back!<br> <br> This is the sort of thing I would expect from China City, not Makro! Or are the boundries blurring?
